A
post from EA Support admits that yesterday's launch of the China Rising
expansion for Premium Members of Battlefield 4 has introduced additional
gameplay issues to the military shooter sequel (thanks
Eurogamer). Also, a
tweet by
DICE's Mikael Hedberg (thanks
reddit) admits the patch for the Windows edition that accompanied the
expansion only partially addressed the one shot kill bug
as intended, as half the
problem is still waiting on fix. He says: "@barklassiebark there's another
related issue. It's not quite the OHK, but it's related to how you die and may
display as a OHK,"
later adding:
"@barklassiebark it looks similar from the target's point of view. we are
testing a fix." Here's the post from EA Help:
